Project Description

Go (or Golang) is an open-source programming language designed to build fast, reliable, and efficient software at scale. It is the language used to create Kubernetes, K3s, Rancher, and countless cloud-native applications. Let's learn Go by writing an application during the hack week!

Goal for this Hackweek

Understand the syntax and grammars of Go
Learn the advanced features of Go
Get familiar with Go’s standard libraries/packages
Write an application following this tutorial

Resources

There are tons of tutorials and articles on the internet, but not all of them are of high quality or up-to-date. If you know any article/book/tutorial that is good for a beginner, please do not hesitate to share them in the comments.

Here are some resources I will use to learn Go:

Contribute to terraform-provider-libvirt by pinvernizzi

Description

The SUSE Manager (SUMA) teams' main tool for infrastructure automation, Sumaform, largely relies on terraform-provider-libvirt. That provider is also widely used by other teams, both inside and outside SUSE.

It would be good to help the maintainers of this project and give back to the community around it, after all the amazing work that has been already done.

If you're interested in any of infrastructure automation, Terraform, virtualization, tooling development, Go (...) it is also a good chance to learn a bit about them all by putting your hands on an interesting, real-use-case and complex project.

Goals

Get more familiar with Terraform provider development and libvirt bindings in Go
Solve some issues and/or implement some features
Get in touch with the community around the project

go-git: unlocking SHA256-based repository cloning ahead of git v3 by pgomes

Description

The go-git library implements the git internals in pure Go, so that any Go application can handle not only Git repositories, but also lower-level primitives (e.g. packfiles, idxfiles, etc) without needing to shell out to the git binary.

The focus for this Hackweek is to fast track key improvements for the project ahead of the upstream release of Git V3, which may take place at some point next year.

Goals

Add support for cloning SHA256 repositories.
Decrease memory churn for very large repositories (e.g. Linux Kernel repository).
Cut the first alpha version for go-git/v6.

Stretch goals

Review and update the official documentation.
Optimise use of go-git in Fleet.
Create RFC/example for go-git plugins to improve extensibility.
Investigate performance bottlenecks for Blame and Status.

Create a Cloud-Native policy engine with notifying capabilities to optimize resource usage by gbazzotti

Description

The goal of this project is to begin the initial phase of development of an all-in-one Cloud-Native Policy Engine that notifies resource owners when their resources infringe predetermined policies. This was inspired by a current issue in the CES-SRE Team where other solutions seemed to not exactly correspond to the needs of the specific workloads running on the Public Cloud Team space.

The initial architecture can be checked out on the Repository listed under Resources.

Among the features that will differ this project from other monitoring/notification systems:

Pre-defined sensible policies written at the software-level, avoiding a learning curve by requiring users to write their own policies
All-in-one functionality: logging, mailing and all other actions are not required to install any additional plugins/packages
Easy account management, being able to parse all required configuration by a single JSON file
Eliminate integrations by not requiring metrics to go through a data-agreggator

Goals

Create a minimal working prototype following the workflow specified on the documentation
Provide instructions on installation/usage
Work on email notifying capabilities

Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy

Description

The Mission: Decentralized & Sovereign Messaging

FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com

In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.

However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.

Why This Matters

A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:

Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.

By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.

Goals

As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.

Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:

Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
Allow the use of bind or remote mounted volumes for shared data (/var/vmail, DKIM keys, TLS certs, etc.).
Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.

By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol

HTTP API for nftables by crameleon

Background

The idea originated in https://progress.opensuse.org/issues/164060 and is about building RESTful API which translates authorized HTTP requests to operations in nftables, possibly utilizing libnftables-json(5).

Originally, I started developing such an interface in Go, utilizing https://github.com/google/nftables. The conversion of string networks to nftables set elements was problematic (unfortunately no record of details), and I started a second attempt in Python, which made interaction much simpler thanks to native nftables Python bindings.

Goals

Find and track the issue with google/nftables
Revisit and polish the Go or Python code (prefer Go, but possibly depends on implementing missing functionality), primarily the server component
Finish functionality to interact with nftables sets (retrieving and updating elements), which are of interest for the originating issue
Align test suite
Packaging

Resources

https://git.netfilter.org/nftables/tree/py/src/nftables.py
https://git.com.de/Georg/nftables-http-api (to be moved to GitHub)
https://build.opensuse.org/package/show/home:crameleon:containers/pytest-nftables-container

Results

Started new https://github.com/tacerus/nftables-http-api.
First Go nftables issue was related to set elements needing to be added with different start and end addresses - coincidentally, this was recently discovered by someone else, who added a useful helper function for this: https://github.com/google/nftables/pull/342.
Further improvements submitted: https://github.com/google/nftables/pull/347.

Side results

Upon starting to unify the structure and implementing more functionality, missing JSON output support was noticed for some subcommands in libnftables. Submitted patches here as well:

Create a go module to wrap happy-compta.fr by cbosdonnat

Description

https://happy-compta.fr is a tool for french work councils simple book keeping. While it does the job, it has no API to work with and it is tedious to enter loads of operations.

Goals

Write a go client module to be used as an API to programmatically manipulate the tool.

Writing an example tool to load data from a CSV file would be good too.

Advent of Code: The Diaries by amanzini

Description

It was the Night Before Compile Time ...

Hackweek 25 (December 1-5) perfectly coincides with the first five days of Advent of Code 2025. This project will leverage this overlap to participate in the event in real-time.

To add a layer of challenge and exploration (in the true spirit of Hackweek), the puzzles will be solved using a non-mainstream, modern language like Ruby, D, Crystal, Gleam or Zig.

The primary project intent is not just simply to solve the puzzles, but to exercise result sharing and documentation. I'd create a public-facing repository documenting the process. This involves treating each day's puzzle as a mini-project: solving it, then documenting the solution with detailed write-ups, analysis of the language's performance and ergonomics, and visualizations.

Kubernetes-Based ML Lifecycle Automation by lmiranda

Description

This project aims to build a complete end-to-end Machine Learning pipeline running entirely on Kubernetes, using Go, and containerized ML components.

The pipeline will automate the lifecycle of a machine learning model, including:

Data ingestion/collection
Model training as a Kubernetes Job
Model artifact storage in an S3-compatible registry (e.g. Minio)
A Go-based deployment controller that automatically deploys new model versions to Kubernetes using Rancher
A lightweight inference service that loads and serves the latest model
Monitoring of model performance and service health through Prometheus/Grafana

The outcome is a working prototype of an MLOps workflow that demonstrates how AI workloads can be trained, versioned, deployed, and monitored using the Kubernetes ecosystem.

Goals

By the end of Hack Week, the project should:

Produce a fully functional ML pipeline running on Kubernetes with:
- Data collection job
- Training job container
- Storage and versioning of trained models
- Automated deployment of new model versions
- Model inference API service
- Basic monitoring dashboards
Showcase a Go-based deployment automation component, which scans the model registry and automatically generates & applies Kubernetes manifests for new model versions.
Enable continuous improvement by making the system modular and extensible (e.g., additional models, metrics, autoscaling, or drift detection can be added later).
Prepare a short demo explaining the end-to-end process and how new models flow through the system.

toki pona programing language by dgarcia

Description

Toki Pona is a philosophical and artistic constructed language designed for its small vocabulary, simplicity, and ease of acquisition.

The idea is to bring the idea of simplicity to a new programing language using this language words and limitations to implement it.

The name for this programming language could be: "toki ilo" or "ilo pona". I will ask the community to get other ideas and also to get feedback about the initial design.

The idea is to start to implement something as a gcc frontend.

Goals

The language design should be really simple but completely functional:
- functions
- variables
- conditional
- loop
- data structures
The keywords should be from toki pona, and better if could be read as pseudo code in toki pona
It should be possible to "compile" code written in sitelen pona
